I came to this phone from an iPhone 11 Max and I am quite happy with the change. Screen size is close enough for me, so I can see a lot but it's not so big as to feel gigantic and a pain for day to day travel and use.
Basically my only complaint is just that the A series seems to have much fewer options for cases. Any of my iPhone I just had to find art I liked on RedBubble or Etsy and it'd be available for that configuration. That seems true for the Samsung S series as well.
But that's my only complaint and considering how good the display and performance of the phone is, the price savings kinda shocked me, so I am very happy with my purchase!
